摘 要:本文分析了三门峡烟区的气候状况,通过定量估算气候适生性指数(CFI),合理评价了烤烟种植的气候适生性,并对三门峡的气候条件与国外优质烟区进行相似性分析,结果表明:①三门峡烟区具有无霜期长,≥10℃积温高,日均温≥20℃持续天数多等特点,具备了生产优质烟叶的基本条件。②三门峡烟区烟叶大田生长期平均温度在20℃以上,日照时数均在900 h以上,降雨充沛,烟叶成熟期昼夜温差大,热量条件可以充分满足优质烟叶生产的需要。③三门峡烟区不同植烟县市的气候适生性指数(CFI)主要表现为卢氏(0.890)>灵宝(0.863)>渑池(0.855)>陕县(0.848);三门峡烟区的气候与国外优质烟区均有较高的相似性,其中与津巴布韦的相似性最高,美国次之,巴西最低,相似性分析为充分利用三门峡烟区的自然资源提供了参考依据。The climatic state of tobacco-growing areas in Sanmenxia was analyzed,and the climatic feasibility in dexes(CFI) were estimated.Analyses were conducted on similarity between climatic conditions of tobacco and corresponding climatic conditions in foreign high-quality tobacco-growing areas.The results indicated that Sanmenxia tobacco-growing areas had a long frost-free period,high accumulated temperature of≥10 ℃,a long period of time with daily average temperature of≥20 ℃.The daily average temperature was about 20 ℃ and the hours of sunshine were more than 900 h during tobacco growing periods.The high sunshine percentage and the abundant rainfall with reasonable distribution were quite propitious to the growth and development of the flue-cured tobacco.The order of CFI for different counties was LushiLingbaoMianchiShanxian,there was a high similarity between Sanmenxia tobacco growing area and foreign high-quality tobacco-growing areas in climatic,showed ZimbabweAmericaBrizal.The similarity analysis may be used as a reference to make full use of the natural resources in Sanmenxia.
